They are constructed from a permanent magnet rotor and three phase stator windings. The commutation is controlled electronically, eliminating the need for brushes that wear out. An incremental shaft encoder is fitted to the rear of the motor to enable closed loop operation.
A selection of 12 motors and 4 drives are available to suit a wide range of applications. The drive parameters are set using a PC and manufacturer software, although minor adjustments can be made on site using push buttons and LED display. The drives are capable of running in velocity, torque and position control (using pulse and direction inputs) modes.
The motors are available with optional failsafe 24VDC brakes. Drive control modes are velocity, torque and postion. The position control is achieved by step and direction inputs (like a stepper drive) so they can be used with low cost pulse output controllers like PLCs and computers.
